I have read this i try next
TabWidget widget = mTabHost.getTabWidget();
for(int i = 0; i < widget.getChildCount(); i++) {
View v = widget.getChildAt(i);
// Look for the title view to ensure this is an indicator and not a divider.
TextView tv = (TextView)v.findViewById(android.R.id.title);
if(tv == null) {
continue;
}
// v.setBackgroundResource(R.drawable.your_tab_selector_drawable);
v.setBackgroundColor(Color.RED);
}
But it only change background color of bottom tabs.

Use android.support.design.widget.TabLayout instead
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/actionbar"
app:tabIndicatorColor="#color/tab_indicator_color" // this is what you want
app:tabIndicatorHeight="3dp" // tab indicator height
app:tabSelectedTextColor="#color/white"
app:tabTextColor="#color/font_color_white70"/>
This has backward compatibility also

ANDROID: Customized tab design crashes app on startup

I have bin trying to customize how my tabs look, and I don't get any errors. But when I try to run the app it crashes. This is what I got:
setContentView(R.layout.activity_main);
tabHost = (TabHost) findViewById(android.R.id.tabhost);
and:
private void setUpTabs() {
// tabHost.setup();
//
// TabSpec spec1 = tabHost.newTabSpec("TAB 1");
// spec1.setContent(R.id.tab_1);
// spec1.setIndicator("", getResources().getDrawable(R.raw.home));
//
// TabSpec spec2 = tabHost.newTabSpec("TAB 2");
// spec2.setContent(R.id.tab_2);
// spec2.setIndicator("", getResources().getDrawable(R.raw.most));
// TabSpec spec3 = tabHost.newTabSpec("TAB 3");
// spec3.setContent(R.id.tab_3);
// spec3.setIndicator("", getResources().getDrawable(R.raw.favorites));
// TabSpec spec4 = tabHost.newTabSpec("TAB 4");
// spec4.setContent(R.id.tab_4);
// spec4.setIndicator("",
// getResources().getDrawable(R.raw.search_icon));
// tabHost.addTab(spec1);
// tabHost.addTab(spec2);
// tabHost.addTab(spec3);
// tabHost.addTab(spec4);
// tabHost.setOnTabChangedListener(this);
setContentView(R.layout.activity_main);
tabHost = (TabHost) findViewById(android.R.id.tabhost);
setupTab(new TextView(this), "Tab 1");
setupTab(new TextView(this), "Tab 2");
setupTab(new TextView(this), "Tab 3");
}
private void setupTab(final View view, final String tag) {
View tabview = createTabView(tabHost.getContext(), tag);
TabSpec setContent = tabHost.newTabSpec(tag).setIndicator(tabview).setContent(new TabContentFactory() {
public View createTabContent(String tag) {
return view;
}
});
tabHost.addTab(setContent);
}
private static View createTabView(final Context context, final String text) {
View view = LayoutInflater.from(context)
.inflate(R.xml.tabs_bg, null);
TextView tv = (TextView) view.findViewById(R.id.tabsText);
tv.setText(text);
return view;
}
The section commented out, is what I did before using the standard tab design.
The .xml parts so far should have no problems, sins that it so far is based 100% on other stuff that I dug up in the net.

private void setupTab(final View view, final String tag) {
View tabview = createTabView(tabHost.getContext(), tag);
TabSpec setContent = tabHost.newTabSpec(tag).setIndicator(tabview).setContent(new TabContentFactory() {
public View createTabContent(String tag) {
final TextView tv = new TextView(this);
tv.setText("Content for tab with tag " + tag);
return view;
}
});
tabHost.addTab(setContent);
}
like this..........

You have to specify the view inside createTabContent{} method........the view returns null thats why its crashing.......

I'm customizing the Tabs and trying to start an activity for each tab. I'm not able to find the error.

try the following code:
final TabHost tabHost = getTabHost();
TabHost.TabSpec ts = tabHost.newTabSpec("ID_1");
ts.setIndicator("1");
ts.setContent(Intent1);// Intent to start activity
tabHost.addTab(ts);
ts = tabHost.newTabSpec("ID_2");
ts.setIndicator("2");
ts.setContent(Intent2);
tabHost.addTab(ts);
ts = tabHost.newTabSpec("ID_3");
ts.setIndicator("3");
ts.setContent(Intent3);
tabHost.addTab(ts);
